Are your Radiation Treatments on Time ?

I’ve gone for treatment 13 times of 44 . I’m receiving Proton Radiation. As many know you show up with a full bladder.
Of the 13 times I’ve gone for treatment , I have had to leave 2 xs without treatment that day -due to machine breakdown with no clear idea of when it would be fixed. Three more times I’ve been delayed anywhere from 25 minutes to 5 hours due to breakdowns.
This is extremely frustrating and uncomfortable - trying to hold your bladder. I don’t really get warnings about how long I’m going to get delayed except 2 xs— they called once and rescheduled on my way down - for 5 hours later, and once 40 minutes after my appt they said they were broke down and could only guess they were going to be at least another hour and a half. I chose to leave as I had to keep emptying my bladder due to urgency. So 5 xs there were some type of delay or no treatment (2) out of 13. Trying to hold your bladder and not knowing how long you have or trying to refill with no clear direction is beyond frustrating.
So my question is - is ANYONE experiencing similar events. I did reach out to 4 different people who had radiation ( 3 not prostate ) and NONE of them experienced delays beyond 5 minutes. I realize there are many variables. At what point do I ask to be transferred to another facility with a better On Time track record AND a crew that bothers to communicate along the way. I don’t like trying to manage my bladder voiding partially and risk damaging bladder. I also don’t like to complain BUT - feel like there is risk with bladder partial voiding
Please share your experience.
Btw. This is NOT at Mayo.
